From 2b31491b10e7b03b98706908566852a62a414a3d Mon Sep 17 00:00:00 2001 From: oyasumi Date: Tue, 18 Aug 2026 01:03:42 +0000 Subject: [PATCH] feat(scope): pass the prompt as the task and inject targets as context, not hard scope Scope was derived from the extracted targets and enforced in the system prompt: the SYSTEM-VERIFIED SCOPE / AUTHORIZED TARGETS block told the agent to test only the listed targets and to ignore any asset named only in the instructions. A prompt that listed several endpoints in prose therefore had most of them treated as out of scope, and the agent refused them. - Remove the SYSTEM-VERIFIED SCOPE / authorized-targets block from the system prompt so nothing gates the agent to a target list. - Rebuild build_root_task: the user's prompt is the task itself (no "Special instructions:" framing). When a target is set it is still injected, but below the prompt as run context ("informs the task above; not a scope restriction"), never as an enforced boundary. On-disk plumbing (repo/workspace paths) and PR diff-scope are unchanged; with no prompt, targets stand as the task. - Drop the now-stale scope-subordination wrapper in _compose_root_instructions_override. build_scope_context still populates authorized_targets for the safety runtime; it is simply no longer turned into scope-enforcement prompt text.
